DESCRIPTION:The goal of the ENSA team is to engineer maize to engage in ni
 trogen-fixing symbiosis to become largely independent of nitrogen fertilis
 ers. The root nodule symbiosis (RNS) for nitrogen fixation evolved from th
 e ancient arbuscular mycorrhizal symbiosis (AMS) with the common symbiosis
  signaling pathway (CSSP) present as a core in both symbioses. Whereas the
  RNS is restricted to almost only leguminous plants\, the AMS is found wid
 ely in the plant kingdom\, including the cereals. We therefore want to int
 roduce the missing requirements for nitrogen fixation into the AM- compete
 nt maize. As a first step we investigated the functional conservation of t
 he genetic components of the CSSP between legumes and the cereals maize an
 d barley\, and the data will be presented. We also reveal data shedding li
 ght on processes linking the availability of the nutrients phosphorous and
  nitrogen with AMS. Our findings are of great importance for a sustainable
  agriculture aiming at diminishing fertilizer use not only in African regi
 ons.
